PUF2 - Polyurethane Foam Sampler
Helping you measure the toxic organic compounds in ambient air.
A sampling instrument that enables measurement of particulates and PCBs and PAH present in the air by entrapping them in Polyurethane Foam as per US EPA Method TO 9A
Available Model : PEM-PUF 2
A PUF Sampler simultaneously collects suspended airborne particulates as well as traps airborne organic vapors such as Pesticides, Polychlorinated bi phenyls-PCBs, Dioxin, Furan and Polycyclic Aromatic Hydrocarbons(PAHS) etc.
Applications :
- Routine Monitoring by air monitoring networks
- Compliance Monitoring in industrial areas
- Vehicular Pollution Monitoring in urban areas
- Monitoring Stations for ISO Compliance
- VOC Monitoring
- Fugitive gas monitoring
- Chemical, Petrochemical, Paint, Cosmetics etc
- Demos and Operation Trainings.
- Evaluative Studies
- Health Impact Studies
Physical Design Highlights
A PUF Sampler comprises a sampling head; a suction blower; a flow measuring device, a flow control device and an Electronic control Module. All these components and assemblies are housed in a sturdy cabinet.
The sampling head is a dual chambered aluminum container which houses both the filtering systems.
The upper chamber supports the airborne particulate filter media in a circular filter holder.
The lower chamber encompasses a glass cartridge which contains the Polyurethane Foam for vapor entrapment.
This dual chambered sampling module is designed for easy access to both upper and lower media. The threaded lower canister is removable with the cartridge intact for immediate exchange. Filter support screens and module components are equipped with gaskets providing a leak proof seal during the sampling process.
